## Abstract

Some comparative numerical calculations of the modified form of the equation of motion versus the Navier-Stokes equation of motion are presented for the problems of laminar boundary layer flow over a flat plate, across liquid and rigid cylinders, and on a rotating disk. It is found that for the all three flow configurations close agreement between the predictions of the modified versus the classical forms of the equation of motion could be achieved. For the flow on a rotating disk, an error in the earlier formulation is identified and a modified formulation is presented that leads to analytical solution for azimuthal velocity in close agreement with the exact numerical calculations of Cochran.
